Rotel’s new RMB-1585MKII 5-channel amplifier continues our heritage of producing high power, audiophile performance amplifiers for multi-channel systems. The RMB-1585MKII delivers unparalleled performance with 5-channels of Rotel Class AB amplification rated at 210 Watts per channel into 8 ohms and an impressive 340 Watts per channel into 4 ohms with all channels driven.
Our summary
Product Strengths
- The RMB-1585MKII delivers 210W per channel at 8 ohms or 340W per channel at 4 ohms, all channels driven
- An oversized toroidal transformer and 120,000µF of filter capacitance ensure clean and solid power delivery
- Thermostat-controlled, variable-speed, low-noise fans keep the amplifier cool
- A bi-amping option is available using channels 1, 2, 4, and 5
- Both RCA and XLR inputs are supported
Product Considerations
- At very close range, a faint hiss can be heard from the tweeter when using the Rotel, though it is not noticeable during regular use
- If not properly ventilated, turning off the fans could shorten the amplifier's lifespan
- Its weight of 82lbs may require assistance when moving or installing
- Those seeking a warm, buttery tube sound or holographic presentation of class-A designs may want to consider other options
Comparisons (according to reviewers)
- Compared to the Anthem AZ7000ES receiver, the RMB-1585MKII produces a bigger soundstage with cleaner details, especially when pushed loud—and a more three-dimensional sound
Takeaway: The Rotel RMB-1585MKII is a powerful amplifier that provides clean and dynamic sound for a home theater or music system. Its robust build and features, like the bi-amping option and cooling system, make it a great choice for taking any system to the next level.

Our take on the brand
Rotel’s new RMB-1587MKII 7-channel amplifier furthers our heritage of producing high powered, high current, exceptionally manufactured Class AB amplifiers for multi-channel systems. The RMB-1587MKII delivers 7 channels of Class AB amplification at 155 Watts per channel into 8 ohms and drives 4 ohm speakers with over 250 Watts per channel, all channels driven.
Our summary
Product Strengths
- Oversized Toroidal transformer allows it to produce the dynamics of a movie soundtrack without running out of power or clipping, keeping distortion low at all volumes
- Smart auto-switching XLR and RCA inputs make installation a simple plug-and-play process
- High-quality gold-plated binding posts for each channel allow users to choose banana plugs or spades
- Thermostat-controlled variable speed low-noise fans keep the amplifier cool, especially when installed in tight rack spaces
Product Considerations
- Turning the fans off might be an option if placed in the listening room and well-ventilated, but it will make the amplifiers run hotter and could shorten their lifespan if the fans are turned off without proper ventilation
- This Rotel is not for someone who likes a warm and buttery tube sound or wants the holographic presentation of great class-A designs
Comparisons (according to reviewers)
- Vs inexpensive class D multi-channel amplifiers, the RMB-1587MKII has a solidity to its sound that one won't find in some of the inexpensive class D multi-channel amplifiers
- Soundstage and imaging were solid—only bettered by much more expensive amplifiers that are dedicated to two-channel audio
Takeaway: The RMB-1587MKII is a solid option for people wanting to take their theater system to the next level, because it delivers clean, solid power with smart features. It will give users years of trouble-free enjoyment.

Our take on the brand
Building on NAD’s long tradition of identifying and developing cutting-edge amplification technology, the M23 HybridDigital Stereo Power Amplifier features Purifi Audio’s Eigentakt™ design, a once-in-a-decade innovation that virtually eliminates harmonic and intermodulation distortion. Noise is inaudible, for a completely black background and exquisite micro-detail. Conservatively rated at 2x200W continuous into 8 ohms and 2x380W into 4 ohms, the M23 can deliver live performance levels through any loudspeaker. With its unique combination of features, performance, and value, the M23 represents the new benchmark for the stereo power amplifier.
Our summary
Product Strengths
- The M23's build quality feels solid and elegant, with impressive small design details
- The sound is striking in its purity and clarity
- It offers up to three levels of gain, switchable on the back panel, to best fit the system
- It provides a clear sound without sounding hard
- It features Purifi Eigentakt Class D amplification, which provides virtually unmeasurable distortion levels
Product Considerations
- The bass is clean but may be perceived as a little on the cool side and not as 'wompy-sounding'
- The M23 is not a forgiving amplifier that makes everything sound sweet and wonderful—it's not for those seeking a soft and mellow sound
- Bridging with speakers below 5 or 6 ohms is not recommended, as the amp will current limit and potentially shut down
- The reviewer found ergonomical challenges using fancy speaker cables in bridged mode due to wide terminal spacing
- The capacitive touch power button can accidentally trigger
Comparisons (according to reviewers)
- Vs Bel Canto C6i: The M23 offered a layer of refinement and better reproduction of the recording space
- Vs Pass XA25: The M23 had more transparent sound and detail, especially in the treble and upper mids, but lacked the organic quality of the XA25
- Vs HiFi Rose RS 520: The M23 sounded cleaner and had better separation/depth, HiFi Rose seemed to have an EQ built-in, emphasizing midrange and bass
- Vs NAD C298: The M23 is more neutral, deals with decay more naturally, and has better casework, making it look high-end
- Vs Anthem M1 monoblock amplifiers: The M23 was slightly more transparent throughout the entire frequency range
- Vs Bryston 4B 3: The Bryston had more grunt but the M23 is more neutral
Takeaway: The NAD M23 is a powerful and precise amplifier that delivers clean and clear sound, making it a great choice for audiophiles who want to hear their music as accurately as possible. It is especially well-suited for those looking to build a high-end system around a quality preamp or DAC.

Our take on the brand
Our Summary
Product Strengths
- Breathtaking design with curved corners, symmetrical front faceplate, and a glass component revealing internal circuitry
- Powerful headphone amplifier capable of outputting up to 10W at 16Ω and 7W at 32Ω
- Good sound quality, described as clean, detailed, and punchy, with a balanced tonal presentation
- CNC machined aluminum remote control with rubber buttons
- Multiple inputs and outputs, including 6.35mm, 4.4mm, and 4-pin XLR outputs on the front, and optical, coaxial, AES, IIS, USB, and Bluetooth on the back, with RCA and XLR outputs for lineout and preamplifier lineouts
Product Considerations
- Glass top panel gets hotter than the aluminum housing
- The glass panel is a fingerprint magnet and requires cleaning regularly
- No analog line-in to pair the amplifier with 3rd party DACs
- No streaming capability via WiFi or LAN
- Some menu navigation can be cumbersome, requiring cycling through options rather than direct selection
Comparisons (according to reviewers)
- Compared to the Topping A90 and D90 stack, the DX9 has similar inputs, outputs and power, but the stack is more versatile, as the amp and DAC can be used separately— the DX9 has additional coaxial and optical inputs, and the sound is somewhat similar
- Compared to the HIFIMAN EF400, the DX9 has more inputs/outputs and more power, but the EF400 sounds warmer
- Compared to the Topping D90SE, the DX9 sounds more fun, its bass and midrange has more energy and oomph, but the D90SE is more transparent, though ultimately quite flat
- Compared to the AURALiC Altair G2.1, the DX9 sounds cleaner and better separated, with a small reduction in digital hash
Takeaway: The Topping DX9 is a beautiful and powerful all-in-one DAC/amp that offers a clean and detailed sound, making it suitable for both headphone and speaker setups. Its versatility and attractive design make it a compelling option for those seeking a high-quality audio solution.
